Mimikatz

[1] Benjamin Delpy discovered a flaw in Microsoft Windows that holds both an encrypted copy of a password and a key that can be used to decipher it in memory at the same time.

[1] A second man approached him during the conference and demanded he give him copies of his presentation and software on a USB flash drive.

[1] Delpy felt shaken by his experiences and before he left Russia, he released the source code on GitHub.

[1] In Windows 10 the feature is turned off by default, but Jake Williams from Rendition Infosec says that it remains effective, either because the system runs an outdated version of Windows, or he can use privilege escalation to gain enough control over the target to turn on the exploitable feature.

Robot episode 9 of season 2, Angela Moss uses mimikatz to get her boss's Windows domain password.
